A three-component reaction of alkenyl thianthrenium salts, cyclopropan-1-ols and DABCO·(SO2)2 under catalyst- additive-free conditions, is accomplished. This sulfonylation with the insertion sulfur dioxide works efficiently very mild leading to a wide range 1-substituted vinyl sulfones in moderate good yields. In this protocol, scope generality salts cyclopropyl alcohols demonstrated.

A cascade reaction of cyclopropyl alcohols, DABSO (1,4-diazoniabicyclo[2.2.2]octane-1,4-disulfinate), and N-(sulfonyl)acrylamides has been developed. This tandem process went through a cyclopropanol ring opening Michael addition sequence. The γ-keto sulfinate generated from the between serves as nucleophilic reagent, N-(sulfonyl)acrylamide is used acceptor. By utilizing this strategy, multitudinous sulfone-bridged 1,7-dicarbonyl compounds that contain both β-sulfonyl amide unit sulfone skeleton were conveniently synthesized.

A visible-light-induced three-component coupling of aldehydes, 1,3-dienes, and cyclopropyl alcohols using dual photoredox chromium catalysis is herein described. This efficient protocol achieves the dialkylation 1,3-dienes toward 1,4-disubstituted homoallylic in moderate to good yields with excellent regioselectivity, featuring mild reaction conditions, functional group tolerance, gram-scale synthesis. Mechanistic study suggests that photoinduced sequential ring opening alcohol radical nucleophilic cascade addition are involved catalytic cycle.
